SlLK-FLOSS HOLDER.

SPECIFICATION forming part of Letters Patent No. 745,296, dated November 24, 1903.

Application filed February 24-, 1903. Serial No. 144,700. (No model.)

2'0 whom it may concern:

Be it known that I, FREDERICK C. RUNGE, Jr., a citizen of the United States, residing at lloughton, county of Houghton, and State of Michigan, have invented new and useful Improvements in Silk-Floss Holders, of which the following is a specification.

My invention relates to improvements in silk-floss holders designed especially for use by dentists.

The object of my invention is to provide an inexpensive form of receptacle in which the floss may be stored and withdrawn as used, but one hand being required for thewithdrawal and separation of the desired length of the filament or thread.

In the following description reference is bad to the accompanying drawings, in which-- Figure 1 is a side View of my invention, partially broken away to show the spool-supporting pin. Fig. 2 is a front view of the same. Fig. 3 is asectional view drawn transversely of the receptacle and spool-supporting pin, and Fig. 4 is a View of the invention as seen from the'under side. I

Like parts are identified by the same reference characters throughout the several views.

The side walls-1 and bottom 2 are formed integrally of a piece of sheet metal stamped into the desired shape and provided with ears 3, having suitable apertures for the reception of screws 4., by means of which the receptacle is secured to any suitable support 5, usually to the under surface of a supporting stand or tray, the support forming the top wall of the receptacle. The rear wall 6 is permanently secured to the side and bottom walls 1 and 2 and is provided with a pin 7, projecting centrally within the receptacle, the pin being socured to the rear wall in any suitable manner. The spool 8, which supports the floss, is adjusted upon the pin 7, as illustrated in Fig. 3.

At the front of the receptacle I provide a hinged lid or door 10, connected with one of the side walls '1 by the hinge 11. The door 10 is provided with an open-sided slot or aperture 12, through which the thread or filament of floss passes to the exterior.

13 is a knife secured to one of the walls 1 and projecting past the edge of the door 10 opposite the hinge 11. This knife is provided with a notch, in which a latch 14, carried by the door 10, is'adapted to engage when the door is closed. The end of the floss thread which projects through the aperture 12 is given one turn over the knob 15, connected with the door, the friction of the thread upon the knob furnishing sufficient resistance to the withdrawal of the floss to enable the operator to sever the thread by drawing it across the knife 13 with one hand. The knob is located at a sufficient distance from th'eknife so that a projecting portion of the thread end will always be left in a position where it can be conveniently grasped by the operator. WVhen the supply of floss is exhausted, it may be readily replenished by raising the latch 14, opening the door 10, and substituting a full spool for the one which is exhausted.

While I have described myinvention with especial reference to its use for holding silk floss, it is obvious that it may be employed for holding any form of thread-carrying spool.

" Having thus described my invention, what I claim as new, and desire to secure by Letters 'Paten t, is-

1. A receptacle having a fixed rear wall provided with an interior spool-supporting pin; a front wall, hinged to one side of the receptacle and provided with a delivery-aperture;
